Electron paramagnetic resonance imaging (EPRI) employed using single-point (SP) imaging techniques offers the capability to dynamically image in vivo tumor oxygenation. While highly specific, current capabilities for high spatial resolution dynamic imaging are limited. Recently, we have investigated partial k-space acceleration techniques for SP-EPRI. In this work, we show that the SP-EPRI imaging technique is highly suited to PF techniques due to its tractable phase characteristics, and that performance of each method is dependent upon image matrix size.
